基于决策试行与评价实验室一Choquet 积分的航班运行风险评价

为提高航空公司安全管理水平，提出一种基于决策实验室分析(DEMATEL)和Choquet Integral耦合的方法对航空公司航班运行风险进行评价。首先在识别航班运行风险因素的基础上，利用DEMATEL方法计算因素的综合影响矩阵。利用综合影响矩阵分别计算因素的影响度、被影响度、中心度和原因度，确定因素的因果属性并确定关键因素。在利用DEMATEL方法计算得到关键风险因素的基础上，利用Choquet Integra构建风险评价模型对航空公司航班运行风险进行综合评价。结果表明，该风险评价模型能够消除风险因素之间的关联性，实现航空公司航班运行风险的合理、有效评价。

Flight Operation Risk Assessment Based on DEMATEL-Choquet Integral

In order to improve the safety management level of airlines, a method based on DEMATEL and Choquet integral coupling is proposed to evaluate the flight operation risk of airlines. Firstly, on the basis of identifying the flight operation risk factors of airline, the DEMATEL method is used to calculate the comprehensive impact matrix of factors. The comprehensive influence matrix is used to calculate the degree of influence, the degree of influence, the degree of centrality and the degree of cause of the factors, and to determine the causal attributes of the factors and the key factors. On the basis of calculating the key risk factors by DEMATEL method, the risk evaluation model is built by Choquet integral to evaluate the flight operation risk of airlines comprehensively. The results show that the risk assessment model can eliminate the correlation between risk factors and achieve a reasonable and effective evaluation of airline flight operation risk.
